Experimental Crystal data

R factor = 0.028; wR factor = 0.077; data-to-parameter ratio = 16.4. In the title compound, [Cu(C6H5BrNO)2]H2O, the CuII ion has a square-planer N2O2 coordination environment. Slipped – stackings [centroid-centroid distances: 3.625 (3), 3.767 (3), 3.935 (3) and 4.255 (3) Å] between pyridine rings and Cu interactions (centroid-to-CuII distance: 3.56 Å) between Cu2+ ions and pyridine rings lead to a layered arrangement parallel to (010). Intermolecular Br O inter-actions [Br O distances: 2.904 (3) and 3.042 (3) Å] and O— H O hydrogen bonds form a three-dimensional network structure
